Abstract / Bemerkung
Using graphical methods based on a ‘lookdown’ and pruned version of the ancestral selection graph, we obtain a representation of the type distribution of the ancestor in a two-type Wright-Fisher population with mutation and selection, conditional on the overall type frequency in the old population. This extends results from [17] to the case of heavy-tailed offspring, directed by a reproduction measure Λ. The representation is in terms of the equilibrium tail probabilities of the line-counting process L of the graph. We identify a strong pathwise Siegmund dual of L, and characterise the equilibrium tail probabilities of L in terms of hitting probabilities of the dual process.
